Canada's biggest model railway, a masterpiece built over decades, will be dismantled - Winnipeg Free Press MONTREAL - In a warehouse in Montreal's historic Griffintown neighbourhood, model train enthusiasts have spent 38 years engaging in a labour of love. Inch by inch, they've constructed what is believed to be Canada's largest fully operational model railway. More than 300 people have participated over the years, devoting thousands of hours to building life-like models across an eye-popping, detail-laden, 1,493-metre masterpiece. And it's about to be detroyed.
